To fix this, we need to increase the port range. When trying to run more than this, the Bluestacks runs out of the ports that it has allowed through the firewall. It seems like the default limit is about 10. This often happens if you are running a bunch of instances.

Does that mask match the one we saw in Step 3? If not, remote that entry and add the correct one & Apply. You will likely see `These IP address` selected, with a single IP mask entered. Go to the `Scope` tab and look in the `Remote IP address` list. Press Start and type in `Firewall` - open Windows Defender FirewallĬlick `Inbound Rules` and look for a rule named `BlueStacks Service Hpyer-V` - double-click it. In the details, you'll see the IPv4 address and subnet mask for this adapter. You should see an entry for BluestacksNetwork - ie, `vEthernet (BluestacksNetwo)` - right click -> status -> details Press Start and type in `Network Connections` - open View Network Connections. However, it often gets this wrong! I don't know why, but I do know how to correct it :) The official help docs give some cut/paste firewall rules that you can try from the CLI, but they don't work if your virtual network ended up in a different IP network. The instances need to be able to communicate with the host process, so the installer attempts to permit this by adding a new rule to the Windows firewall. Hyper-V creates a private network for VMs, and BlueStacks creates it's own second private network. This is usually due to a problem with how the BlueStacks installer configures your firewall. I've been struggling with Bluestacks Hyper-V startup issues and finally found a solution! There are three types of issues:Ĭan't run some cloned instances simultaneously
